HOOP-COILING MACHINE.

SPECIFICATION forming part of Letters Patent No. 566,506, dated August 25, 1896.

Application filed September 23, 1895. $erial1Io. 563,436. (No model.)

To all whom it may concern:

Be it known that I, GEORGE A. ENSIGN, of Defiance, in the county of Defiance and State of Ohio, have invented certain new and useful Improvements in Hoop-Coiling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in hoop-coiling machines, the object of the invention being to produce a machine of the class specified which shall be simple in construction, easy to manipulate, and effectual in all respects in the performance of its functions.

With these objects in view the invention consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a machine embodying my improvements. Fig. 2 is a horizontal sectional View. Figs. 3, 4, and 5 are detail views.

A represents a frame having an upwardlyprojecting flat plate or casting A, made V- shaped in general form and terminating at its upper end in an arm 1, having a laterallyprojecting cushion 2 secured thereto for a purpose hereinafter explained. The plate or casting A is made with a large opening, and concentric with this opening a plate 3 is disposed and provided in its center with an opening for the accommodation of a shaft 4, secured to said plate. The shaft 4 also passes through a sleeve 5, supported by a bearing 6, and is extended some distance beyond the rear end of the sleeve and mounted in a bearing 7 on the frame A. The sleeve 5 extends through a cross-bar 8 and is provided at its rear end with a head 9, which bears against said cross-bar, said head being perforated for the accommodation of the shaft 4. At the front side of the crossbar 8 a collar 10 is secured to the sleeve 5 by means of a suitable set-screw 11. The ends of the cross-bar S are secured to rods or bars 12 12, loosely mounted in bearings 13 13 on the frame and 14 14 in the plate A.

The rod or bar 12 extends beyond its bearing in the plate A, and at its free end is screwthreaded for the accommodation of a perforated boss 15 on a vertically-movable gate B, a nut 16 being placed on said rod or bar and bearing against the gate B. The diametrically-opposite side of the gate B is provided with a hook-shaped boss or enlargement 17, adapted to engage the free end of the rod or bar 12, and when in this position said hook bears against a washer 18 on said rod or bar 12, and is retained in position by means of a lever-nut 19, screwed on the end of the rod or bar. The shaft 4 is provided with a drum 20, disposed in the space between the gate 13 and the framework, and having suitable devices whereby to attach the end of a hoop to be coiled to said drum. A spider 21 is fixed to the end of the sleeve 5 (through which sleeve the shaft 4 loosely passes) and projects loosely through the plate 3, said spider being so constructed that when moved forward it will receive the drum 20 and force the coiled hoop therefrom in a manner hereinafter more fully explained.

A loose pulley C6 is mounted on a shaft 4 and provided with a flange a,adapted to have frictional contact with a friction-wheel. a secured to said shaft. The loose pulley is made with a grooved sleeve o for the reception of pins o projecting from a yoke a carried by a laterally-projecting shaft a To the free end of the shaft of a lever a is secured, and to the free end of' said lever a rod or pitman a is attached. A shaft or pintle a is mounted in the lower portion of the frame A and provided with a short arm a to which the lower end of the rod or pitman a is attached. The free end of the shaft of has a treadle a secured thereto, by means of which the loose pulley can be moved toward the frictionwheel to cause the starting of the shaft 4 and the hoop-drum carried thereby. The pulley is moved in the other direction by a spring 48.

An arm 22 is disposed in front of the plates A 3, and is held in position by means of a stud 21 which passes through a hole in plate A and enters a socket in a lug 23,made on the back of said plate A, in which socket the stud 21 is secured by a set-screw 24 or in any other suitable manner. From its connection with theframework, the arm 22 projects upwardly and inwardly over a portion of the plate 3 and at its upper end is provided with a pin 25, projecting toward said plate 3. A

coiling-strap 26 is provided at one end with an eye 27 to fit over the pin 25. By means of this attachment of the coiling-strap the same can be easily and quickly removed by loosening the set-screw 24 (or other fastening device which may be used) and removing the pin or stud 21 The upper end of the coiling-strap is removably attached to a lever 28 between the ends of the latter. The lever 28 is pivotally connected at one end to the upwardly-projecting portion of the plate or casting A, and the pivoted end of said lever is provided with an involute head 29, to which one end of a spring 30 is connected, the other end of said spring being attached to an arm or projection on the plate or casting A. From this construction and arrangement of parts it will be seen that as the hoop is coiled upon the drum 20 and within the coilingstrap 26 the power or force of said spring on the coiling-strap will be equalized by the involute head to which said spring is attached, said head forming the short arm of the lever to which said coiling-strap is attached.

A bell-crank lever 31 is connected with a shaft 32, mounted in the framework A, and one arm of said bell-crank lever is connected by means of a link 33 with the crossbar 8. The other arm of the bell-crank lever is connected by means of a rod 34 with a treadle 35, mounted loosely on the shaft a". From this construction and arrangement of parts it will be seen that when the treadle 35 is depressed the cross-bar 8 the rods or bars 12 12, carrying the gate B,and the sleeve 5,carrying the spider 21, will be moved forward and the spider will force the coiled hoop off of the coiling-drum and permit it to drop from the machine; but before this operation is performed it is desirable that the free end of the hoop be secured, and for this purpose a nailing-finger 36 is provided. The nailingfinger 36 is pivotally connected with the plate A and normally held in an elevated position by means of a spring 37 on the back of the machine, and is connected by a rod 38 with a treadle 39, by means of which to operate it.

In operating the machine the end of a hoop is secured to the coiling-drum by means of any suitable fastening device and the treadle a depressed to start the rotation of the shaft 4 and the coiling-drum 20, carried by said shaft. When the coil is of the proper size, the pressure on the treadle a is relieved and applied to the treadle 39, and the last hoop is stopped at a point under the nailing-finger, the hoop-being held by said finger while the operator drives a nail into it, and then the pressure on the lever or treadle 39 will be relieved, the operator meanwhile holding the lever 28 with his right hand. The operator then quickly applies pressure to the treadle 35, whereupon the coiled hoop will be forced from the machine, as above explained. When the operator depresses the treadle 35, he re leases the lever 28, whereupon the latter will assume a vertical position against the stop. The treadle 35 will then be released and allowed to assume its normal position by means of a spring 48, and the sliding rods, cross-bar, and spider will then be carried back quickly by means of said spring 48. The parts being thus forcibly carried back to their normal positions, it is desirable that some means be provided for cushioning this return movement of the parts. For this purpose I prefer to employ a dash-pot, the head 9 011 the sleeve 5 forming the piston of said dash-pot. The cylinder 41 of the dash-pot is secured to the shaft 4 and made with airopenings 42, and provided with a leather washer 43, against which the head or piston 9 normally rests, said washer being held in an annular groove 44 in said cylinder.

My improvements are very simple in construction, comparatively cheap to manufacture, and effectual, in all respects, in the per formance of their functions.

Slight changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope, and hence I do not wish to limit myself to the precise details herein set forth; but,

Having fully described my invention,what I claim as new, and desire to secure by Letters Patent, is-

1. In a hoop-coiling machine, the combination with a frame, and a shaft revolubly supported therein said shaft having a coilingdrum thereon, of a sleeve in which the shaft turns, said sleeve having a spider on one end and a head on the opposite end, and a cup or cylinder secured on the shaft in position to receive the head on the sleeve when moved in one direction, substantially as set forth.

2. In a hoop-coiling machine, the combination with a frame, and a shaft revolubly supported therein and having a coiling-drum on one end and a driving-pulley on the other end, of a sleeve in which the shaft turns, said sleeve having a head on one end and a spider 011 the other end, a cup or cylinder to receive the head, a cross-bar, rods or bars secured to said cross-bar, and bearings in which these rods or bars move, substantially as set forth.

3. In a hoop-coilin g machine, the combination with a frame and a revoluble coilingdrum, of an arm connected with the frame, a coiling-strap connected to this arm, a pivoted lever to which the opposite end of this strap is connected, said lever having an involute head thereon, and a spring secured to the head and passing around it and secured to the frame, substantially as set forth.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
